WLADYSLAW NIGBOROWICZ, OF GALLITZIN, PENNSYLVANIA.

MULTIPLE-SOCKET WRENCH.

To all whom it may concern:

Be it known that I, WLADYsLAW NIGBoRowIoz, a subject of the Emperor ofAustria- Hungary, residing at, Gallitzin, in the county of Cambria andState of Pennsylvania, have invented certain new and useful Improvementsin Multiple-Socket Wrenches, of which the following is a specification.

This invention relates to certain newand useful improvements in multiplesocket wrench. 1

The primary object of the invention is to provide a ratcheting socketwrench that is readily reversible and easily adjusted for theaccommodation of turn nuts of different versible socket wrench having anoperating ratchet handle and provided with a plurality ofdifferent-sized receiving sockets selectively positionable forindividual use and projectingly positioned when desired for operation. 7

A still further object isto provide amain socket wrench of the ratchettype carrying a plurality of telescoping socket members of graduatedsizes, such socket members being preferably projected whenever thewrench is desired for use.

With these general objects in view and others that will appear as thenature of the invention is better understood, the same consists in thenovel combination and arrange-.

ment of parts hereinafter more fully described, illustrated in theaccompanying drawings and pointed out in the appended claims.

In the drawings forming a partof this application and in which likedesignating characters refer to corresponding parts throughout theseveral views ;F igure 1 is a face view of the device with the handlepartially broken away and with parts shown in longitudinal section.elevation thereof. Fig. 3 is a perspective sectional view taken uponline IIIIII of Fig.2. Fig. 1 is a side elevation of the socket membersremoved from the device and in their projected positions, and Fig. 5

mediate threaded perforations 17 are-pro'-' vided therein at pointsadjacent its opposite end faces 18. A ratcheting pawl or 'dog 19 11 bymeans of a-transverse pin 21 and carries inwardly projecting teeth22which are normally maintained within the path of travel of theoutersurface ofthe hub 15 and ratchetingly' engageable with the grooves16' by'means of a helical expansion spring 22 maintained within thesocket 20 and in constant engagement with the heel 23 of the said pawl.By this'arrangement it will be seen that thehub 15 may be readily turnedin one direction by means of the handle 11, while any resistance exertedupon the hub will allow the handle to ratchet thereover in its returnmovement, the inclined faces 24 of the pawl teeth 22 freely slippingover the edges of the said grooves 16 during. such forcible movement ofthe handle. I r

The hub 15 is provided with an axial opening 25 extending therethroughand forming a nut-receiving socket, the said opening being of anydeslred shape and cor responding with the shape 'ofthe nut to beis'pivoted within asocket 20 of the handle i operated upon and hereinillustrated as hexagonal in form. .A wrench sleeve 26' is slidablypositioned being also hexagonal in form withinthe said hub opening 25and is provided with a nut-receiving hexagonal opening 27 extendingaxially therethrough and being of less "dimensions than the huoSimilarly, a second wrenchopening 25. v sleeve 28 is slidably mountedwithin .the afore-mentioned sleeve 26 and has a hexagonal nut-receivingopening 29 therethrough and in this opening an innermost wrench sleeve30 is slidably positioned having a relatively small nut-receivingopening 31 I therein which is thereby arranged centrally of the hub 15.I j

The hub opening '25 is provided with a longitudinal groove 32 thereinadapted to slidingly receive a longitudinal rib 33, while the sleeves 28and 30 are provided with similar ribs 34 and 35 respectively adapted forsliding reception within corresponding grooves 86 and 37 respectively,of the sleeves 26 and 28. By reason of the hexagonalshape of theseparate sleeves 26, 28 and 30 as well as the receiving hub opening 25and the guiding lugs 38, 34k and 35 it will be seen that while thewrench sleeves and hub are relatively slidably positioned, all relativerotation between any of the said members is positively prevented.

A means is provided for the prevention of a separation of the hub 15 andthe several wrench-sleeves which consists of interengaging screws andgrooves, it being noted that the screw 38 is carried by the hub 15,being positioned within one of the grooves 16 thereof and freelyextending within a longitudinal valley, 39 of the hub-carried sleeve 26and while a similar screw 40 is carried by the sleeve 26 and extendswithin a valley 4C1 of the sleeve 28 and similarly, a screw 42 carriedby the sleeve 28 extends within a valley 4:3 of the inner sleeve 31.

It will be thus evident that while the sev eral sleeves may be projectedas illustrated in rigs. 4i and 5 the same will be retained from beingdisassembled from the hub 15 and it will be also seen that the hubopening 25 may operatively engage a turn nut when the sleeves 26, 28 and30 are moved inwardly of either end of the hub opening, while the sleeve26 may be readily adjusted by being projected for the reception of a nutwithin its socket opening 27, it being under stood that the sleeves 28,and 30 will then be allowed to, remain in substantially their normalclosed position within the hub 15.

lso, the sleeves 26 and 28 may be projected and the sleeve 30 positionedinwardly of the sleeve opening 29 when desired to use the said opening29 as a socket for receiving the nut, while of course, the centralopening 31 may be operatively employed by projecting the inner sleeve 31to its extreme outward position as illustrated in, Figs. 4 and 5 of thedrawings, or in intermediate projected positions or even in its normalinclosed position within the hub as illustrated in Fig. 1.

When desired to look all of the sleeves in position within the hub 15, aset screw 14 maybe employed threaded within one of the hub openings 17and passing through a similar opening d5 of the sleeve 26 and 16 of thesleeve 28 and bear within a socket 4:7

and at which time however the inner sleeve 30 will be freelypositionable.

It will be evident that many different combinations of relativepositions of the wrench sleeves may be arranged for adapting the devicefor use in connection with different sized nuts and for engagement atdifferent sides of the wrench, it being seen that the Wrench hub 15 maybe turned in opposite directions by using a reverse one of the hub faces18 for engaging the nut, although the ratcheting pawl 19 allows thehandle 11 to actuate the hub in a uniform direction. It will be alsonoted that a finger-hold 51 is provided upon the heel 23 of the pawl 19whereby the teeth 22 of the pawl may be readily released from the groove16 of the hub, and the hub thereby readily removed from the collar 10.

VVhile the form of the invention herein shown and described is what isbelieved to be the preferred embodiment thereof, it is nevertheless tobe understood that minor changes may be made without departing from thespirit and scope of the invention as claimed.

What I claim as new is l. A ratchet wrench comprising a hub having anengaging opening extending therethrough, a plurality of double-endednut-receiving sleeves telescopingly adjustably positioned within thesaid opening, cooperating rotation preventing means carried by thesleeves, and means for locking he sleeves in extended and retractedadjusted positions.

7 2. A ratchet wrench comprising a collar, a cylindrical hub journale'dtherein and having an angular nut-receiving opening therethrough, aplurality of telescoping Wrenchsleeves of similar configuration slidablypositioned within the said opening, cooperatmg tongues and groovesformed on the opposed faces of the sleeves, and means for locking thesleeves in extended and retracted adjusted positions.

8. A ratchet wrench comprising a cylindrical hub, having a nut-receivinghexagonal opening axially extending therethrough and having spacedlongitudinal grooves upon its outer surface, a sleeve encircling thesaid hub and removably positioned thereon, a spring-pressed releasingand ratcheting pawl attached to the said sleeve and in operativeengagement with the said grooves, a plurality of telescopingwrench-sleeves slidably positioned within the saidhub opening and beingeach formed hexagonal in cross-section, guide tongues and groovescarried by the opposed faces of each sleeve, and means for locking thesleeves in eXtended and retracted adjusted positions.

a. A ratchet Wrench comprising a cylindrical hub, having a nut-receivinghexagonal opening axially extending therethrough and having spacedlongitudinal grooves upon its outer surface, a sleeve encircling thesaid hub and removably positioned thereon, a spring-pressed releasingand ratcheting pawl attached to the said sleeve and in operativeengagement with the said grooves, a plurality of telescopingwrench-sleeves slidably positioned within 10 the said hub opening andbeing each formed hexagonal in cross-section, longitudinal lug justablelocking means between the sleeves 15 whereby the hub and sleeves may belocked in any adjusted position.
